The index shows the rate of coastal erosion of the coastline of the Caribbean, Pacific and insular areas of Colombia. Conceptually, the variables considered to develop the statistical operation are based on: i) Distance (spatial variation between coastlines - meters), ii) Time (number of years between coastlines - years) and iii) Thematic segments of the territory (geomorphology, ecosystems, population, among others). Methodologically, there are 3 main components, which are remote sensors, the platform for processing and automation of satellite images and finally the GIS (Geographic Information Systems), the latter will allow the development of Geostatistics, obtaining results such as erosion rates, percentage of the country's coastline in erosion, by region, by the department, geomorphological units and ecosystems, among other data. Finally, the analyzes are carried out at the national, regional (Caribbean, Insular and Pacific) and departmental levels (12 coastal).
